No, we are not running cloud-setup-agent manually. I believe when we set up things on the management UI, it kicks of cloud-setup-agent programmatically. We'd like to identify the piece of code that takes over eth0 and disable it if possible. cloud_utils.py has some code that did this (there's a part that sets up a bridge and makes the default interface a member), but removing that code seems to have had no effect.
